B68-270 GRAVITY INCLINOMETER. Kern Patent. Patented in 1906 by Bernard Kern, Jr., of Toledo, but marked only with the patent year like all known examples. This is one of the most attractive and gizmoish of the patented inclinometers with its adjustable central vial assembly and mantle clock shape. They used common softwood for the body, and many of them have significant wear, but this one has an attractive reddish finish and is one of the cleanest examples we've seen. Fine 400-800
